Abstract: An optical imaging lens, in order from an object side to an image side along an optical axis, includes a first lens assembly, an aperture, and a second lens assembly. The first lens assembly includes a first lens having negative refractive power, a second lens having negative refractive power, and a third lens having positive refractive power. The second lens assembly includes a fourth lens having positive refractive power, a fifth lens having negative refractive power, a sixth lens having negative refractive power, and a seventh lens having positive refractive power. The optical imaging lens satisfies: -0.05<F/fg1<-0.3-; F is a focal length of the optical imaging lens and fg1 is a focal length of the first lens assembly, thereby achieving the effect of high image quality.

Abstract: An optical imaging lens, in order from an object side to an image side along an optical axis, includes a first lens assembly, an aperture, and a second lens assembly. The first lens assembly includes a first optical assembly having negative refractive power, a second optical assembly having negative refractive power, a third optical assembly having positive refractive power. The second lens assembly includes a fourth optical assembly having positive refractive power and a fifth optical assembly having positive refractive power. Two of the first optical assembly, the second optical assembly, the third optical assembly, the fourth optical assembly, and the fifth optical assembly are a compound lens formed by adhering at least two lenses, while the others are single lenses, thereby achieving the effect of high image quality.
